Teeth whitening is often referred to bleaching. helps remove stains and discoloration of teeth. One of the most popular cosmetic dental procedures that can greatly improve how your teeth look is whitening. Most of the dentists perform tooth whitening. There will be not cutting or etching of a dental enamel. It is a one-time process and will need to be repeated from time to time in order to maintain the brighter color.
Why is Teeth Whitening Needed?
- Teeth whitening is often needed in cases of heavy consumption of discoloring substances such as alcohol, red juices, tea, coffee, cola, red wine, mustard or ketchup as well as poor oral hygiene.
- Two chemicals are found in tobacco that create stubborn scars: tar and nicotine. Tar is naturally dark. Nicotine is colorless until it is mixed with oxygen. Once mixed with oxygen it turns into a yellowish surface staining substance. Researches on the effect of smoking on teeth discolouration have proven beyond doubt, the relationship between tobacco and stained teeth
- Age also is a reason to need teeth whitening. Enamel is the strongest substance in human body. And our teeth are coated with enamel. But below this hard outer layer there is a soft layer beneath it and it’s called dentin. Overtime the outer layer also gets thinner with brushing and more of the yellowish dentin shows up.
- Any dental injury, if you have been hit or injured there will be a change in the color which makes the dentin layer look more observant.
- Medications that have side effects also may be a reason for the discoloration of teeth. A side effect of certain antihistamines, antipsychotics and high blood pressure medications can be tooth darkening. Also, young children who are exposed to antibiotics like tetracycline and doxycycline while their teeth are forming(either in the womb or as a baby) may have discoloration of teeth later in their adult life.
- Chemotherapy and head & neck radiation can also darken teeth. [Study]
Other dental problems can affect the success of tooth whitening. For example, cavities need to be treated before teeth are whitened. That’s because the whitening solution can pass through decayed areas and reach the inner parts of the tooth. If your gums have receded, the exposed roots of your teeth may appear yellow or discoloured. Whitening products will not make them whiter.
Teeth Whitening is normally done in the dental office. However, you can also do teeth whitening at home
For in-office whitening, your dentist probably will photograph your teeth first. This step will help him or her to monitor the progress of the treatment. Your dentist also will examine your teeth and ask you questions to find out what caused the staining.
Few times tooth whitening is affected by other dental problems.Let’s take an example, in any process tooth cleaning the procedure is started by treating cavities. In tooth whitening also the cavities are checked and treated at first so that even the inner parts of the tooth including decayed areas can get the whitening solution. The exposed roots might appear yellow or discoloured if the gums are receded and for this whitening products may not help.
Process of tooth whitening can be done at home or office. While in office photographs will be taken, also your doctor will ask you questions, to know about the stains.
Teeth Whitening Options
- Consult your doctor before using any of the following options to whiten your teeth.
- There are few stain removal toothpaste that helps remove the surface stain through scrubbing and addition of mild abrasives. These toothpastes also have additional polishing agents that are safe for the teeth and provide stain removal effectiveness. These toothpaste have the seal of ADA[American Dental Association] acceptance. Unlike bleaches these tooth paste do not help whiten the teeth, they just help remove the stains.
- Chairside bleaching usually requires only one office visit. The dentist will apply either a rubber shield or a gel to your gums and then apply the bleach to your teeth. Also known as in office bleaching.
- Bleaching can also be done at home under the instructions of your dentist. Instructions would be how to place the bleach solution on to your teeth and for how long. This might be an option based on your comfort zone and the time you want to spend either at the clinic or at your home at your own leisure timings.
- Over the counter bleaching products include the products available in the market that help bleach your teeth such as toothpaste and strips. These are safe as they are certified by ADA but again the concentration of bleaching powder within them is very less compared to that of what the dentist uses in the clinic. Though these products are effective and safe to use do not forget to consult your dentist before using any of the product.
- The whole of the whitening product consist of two tooth bleaches viz., hydrogen peroxide and carbamide peroxide. These two bleaches break stains into smaller pieces which makes the color less concentrated and your teeth start looking bright.
Does Whitening Work on all the Teeth?
Whitening might not work on all teeth, which is why it is important to talk to your dentist regarding your tooth issues. These whiteners may not correct all kinds of discoloration. For example, yellow teeth may probably bleach well and brown teeth might not respond so well as expected and teeth with grey tones may not get bleached at all. So, it depends on the color of your teeth whether the teeth can be whitened or no. whitening won’t be effective if the discoloration is due to medications and injury. It also won’t work on caps, veneers, crowns or fillings.
Overuse of whiteners can damage the tooth enamel or gums, hence it important to be sure and follow the instructions of a dentist. In most cases people might face tooth sensitivity, this happens when the peroxide in the whitener gets through the enamel to the soft layer dentin and starts irritating the nerve of the tooth. Also, women should avoid whitening teeth while they are pregnant because, the effect of whitening material on the development of fetus is not known yet. Since the procedure is cosmetic, to avoid risk it should be postponed until after delivery.
